It's a clip from the movie the Nightmare Before Christmas.
Jack Skellington, ruler of Halloween, took over Christmas and was inadvertently terrorizing children. The military got together and started launching missiles at him. Jack mistook them to be celebrating and thought they were thanking him for doing such a good job.
It wasn't until it was a little too late did he realize they were actually trying to shoot him out of the sky.

It was a gif I quickly and lazily made and FunnyJunk busted up the rest.
